Integration options for novel chemical looping air separation (ICLAS) process for oxygen production in oxy-fuel coal fired power plants

► Thermodynamic process simulations were carried out in this paper. ► Several integration options have been derived for integrating ICLAS with oxy-fuel. ► Effect of key operating parameters and heat sourcing options have been examined. ► Oxygen concentrations in the product stream have been calculated. ► Results indicate that ICLAS can produce O2 at much lower costs compared to CASU.
